Guide Step-by-Step:

This guide provides quick instructions for configuring audio on the Aorus Z390 Pro motherboard using a patched DSDT file. For best results, use alcid=29 in your boot arguments, which is known to work well with this setup.

Step 1: Verify DSDT and OpenCore Setup

1. Download or Apply Patched DSDT:

   • Use the patched DSDT specifically tailored for the Aorus Z390 Pro. Place it in EFI/OC/ACPI.
   • Make sure ACPI > Add in config.plist is set to include the patched DSDT file.

2. Kexts Required:

   • Ensure AppleALC.kext is in EFI/OC/Kexts for onboard audio support.
   • Also, include Lilu.kext to ensure compatibility and proper patching.

Step 2: Set alcid=29 in Boot Arguments

1. Open config.plist with ProperTree or OpenCore Configurator.
2. Under NVRAM > boot-args, add:

   text
   Copy code
   alcid=29
   

3. Save and close the config.plist.

Step 3: Reboot and Test Audio

1. Reboot your system.
2. Once booted into macOS, go to System Preferences > Sound.
3. Verify that audio outputs (such as line-out, headphones, and HDMI audio if supported) are recognised and functional.

Troubleshooting

• If audio doesn’t work:
  • Confirm AppleALC.kext and Lilu.kext are in the correct folder.
  • Ensure alcid=29 is correctly entered in boot arguments.
  • Try alternative layout IDs like alcid=1 or alcid=11, though alcid=29 is typically reliable on the Aorus Z390 Pro.

This setup should get your Aorus Z390 Pro audio running smoothly with the patched DSDT. Let me know if you need more specific help with other DSDT settings!
